Subject: [PATCH] Prevent t6000 series from dropping useless sed.script in t/

The Makefile in the test suite directory considers any file
matching t[0-9][0-9][0-9][0-9]-*.sh as the top-level test script
to be executed.  Unfortunately this was not documented, and the
common test library, t6000-lib.sh was named to match that
pattern.  This caused t6000-lib.sh to be called from Makefile as
the top-level program, causing it to leave t/sed.script file
behind.  Rename it to t6000lib.sh to prevent this, and document
the naming convention a bit more clearly.
